"Work on the peninsula? Interested in riding your bike to work? Then come join the SF2G group (SF to Google) for their monthly First Friday Friendly Frolic! FFFF is a fun, low-key, no-rider-left-behind commute from SF to points down the peninsula -- San Mateo, Foster City, Palo Alto, Mountain View, Cupertino, etc. SF2G takes a nice, flat-ish route out of the city, sticking mostly to bike paths and marked bike lanes, and at a moderate pace everyone can handle. Approx. 9:30am arrival in Mountain View."
